3. Petzl Sitta

4.5/5 Overall Rating

At 275 grams, the Petzl Sitta is remarkably light. This harness is geared towards mountaineering and climbing and offers maximum comfort and compactness in a lightweight package.

The design allows for optimal weight distribution without the use of foam because Spectra strands are used in the leg loops and waist belt.

This ‘Wireframe technology’ uses parallel strands of strong and ultralight Spectra to distribute the load over the waist belt and leg loops.

The super sleek design focuses on compactness and the bonded fabric helps to avoid pressure points and offers optimal wear resistance.

The harness also features reinforced tie-points to resist the wear and tear from rope friction.

Because of the nature of the harness it has minimal gear loops and features practical details like separated gear loops and a leg loop height adjuster.

The Edelrid Jay II is the ideal generalist and top beginner harness you can find. It combines good comfort and great features at an attractive price. 

The harness is stable and supportive and has adjustable leg loops for full customization.

The sliding belt design, which allows the main belt to slide through the frame of the padding, helps to keep your gear and belay loops centered.

The harness has a lower tie-in point which is bolstered by a rigid plastic semicircle which makes the harness a little more durable.

The Edelrid Jay II is best for sport or trad climbing and utilises 3D mesh padding to give your harness extra support. It also has glider buckles on the waist belt and leg loops which allow for adjustments.

5. Black Diamond Solution

4/5 Overall Rating

The Black Diamond Solution, which is a favorite for sport climbing, is known for its unrivalled comfort and affordable price.

It utilises Fusion Comfort Construction, a design that employs three very thin strips of webbing spread out through the waist belt and leg loops to help diffuse pressure on the back, hips and hamstrings. The design moves with your body while providing load distribution and comfort.

The leg loops and waist belt are wide for support and comfort and the material is quick-drying and breathable.

Although incredibly comfortable, the Black Diamond Solution does come with a few downsides, the minimal gear loops and lack of haul loop mean the harness is not a good choice for long-free or alpine climbs.

But if you are looking for the best sport climbing harness, the Black Diamond Solution is the best you can get.

What we dislike
  • Small gear loops
  • Not versatile for other styles of climbing
Key Takeaway

The Black Diamond solution is the most comfortable harness you can buy. But it is best for sport climbing and may not be a great choice for other types of climbing.

Climbing Harness Buyer's Guide

Below is information on what you want to consider before you purchase a climbing harness to ensure you make the right choice for your personal climbing needs.


Different harnesses are used for different climbing sub-disciplines.

Alpine Rock

Big Wall 

These harnesses tend to be pricier, as they will have all the bells and whistles.


You will be looking for a harness that is comfortable, durable and inexpensive. You will not need a bunch of fancy features with a gym harness, however, you will want a harness that has good padding.


A mountaineering harness should be minimalistic, lightweight and easy to get on and off. You will also want a harness to be comfortable to walk in.


Like a mountaineering harness, you will want a minimalistic harness that allows for freedom of movement. Smaller gear loops won’t be a huge issue.


These will be more full-featured harnesses. They will need to have at least 4 gear loops and a rear haul loop along with a wide waist belt and leg loops.

Size & Compfort

Having a well-fit harness is absolutely critical for safety while you climb. The waist belt shouldn’t slide over your hips if you were to flip upside down.

The comfort of your harness can greatly improve your climbing experience.

Leg Loops

Leg loops will either be fixed or adjustable. Many people prefer fixed leg loops at they are less bulky, lighter and easy to take off and put on. But fixed leg loops may not be suitable for all body types. Adjustable leg loops are best if you don’t fit comfortably in fixed leg loops. Adjustable leg loops also make it easier to layer clothes.

Gear Loops

Gear loops make climbing life more convenient. It is essential to have at least 4 gear loops if you will be climbing outdoors to ensure you have easy access to all your equipment. You’ll want larger, sturdier loops.


The weight you want your harness to be comes down to personal preference, but a lot of people prefer lightweight, less bulky harnesses.
